Start from a low level of net carbs to ensure you quickly enter ketosis (~ 20 grams of net carbs per day). When you detect ketosis after about 2-3 days, start adding net carbs (about 5 grams each week) until you detect a very low-level or no ketones (using Ketostix or blood ketone meter).
Eating 100 grams of carb a day is as close to nutritional magic as you can get: It's Low-Enough Carb. At 100 grams of carbs per day, you won't be in ketosis, but your carbs will be low enough that you'll be preferentially stoking your metabolic furnace with stored and dietary fats and not carbs.
